Set oven to warm, or to 150 degrees. After greasing a large bowl with butter, pour in the rice krispy cereal and place in the oven. The cereal will begin to warm while you start on the marshmallow fluff making it easier to mix later in this process!
175 g Rice Krispies Cereal
In a small bowl, mix gelatin, 2 tablespoon water, and coconut extract with a fork.
2 teaspoon Unflavored Gelatin Powder, 2 tablespoon Cool Water, 2 teaspoon Coconut Extract
Combine the sugar, water, corn syrup, and salt in a pot. Turn on the stove to medium-high and heat until bubbling. Continue to cook without stirring until the mixture reaches 250 degrees Fahrenheit.
60 g Water, 170 g Light Corn Syrup , 200 g Granulated Sugar , ½ teaspoon Salt
Pour the hot syrup into the bowl of your stand mixer and cool until your thermometer reads 212 degrees. Add the gelatin mixture into the sugar syrup and mix with the whisk attachment on low speed to combine. Once homogenous, increase the speed to medium-high and continue whisking until the syrup is thick and glossy. This should take 5-8 minutes.
Grease your 8x8 pan while you wait for the marshmallow fluff to finish mixing.
Add coconut flakes, coconut dulce de leche and softened brown butter to the marshmallow fluff and whisk to combine.
55 g Brown Butter , 60 g Coconut Dulce de Leche , 25 g Unsweetened Coconut Flakes
Grab the warmed cereal from the oven and pour your coconut marshmallow fluff into the bowl with the cereal. Using a spatula sprayed with oil, fold the cereal into the marshmallow fluff gently until combined.
Transfer the mixture into your prepared pan and sprinkle the toasted coconut flakes on top, gently pressing to the top of the rice crispy treats. Cover with plastic wrap and allow to rest and ingredients to cool/firm for 1-2 hours.
Remove the rice crispy treat square from its mold and set on parchment paper. Take the melted chocolate and drizzle on top of the toasted coconut flakes. Then, cut into pieces using a serrated knife. Wrap leftovers in plastic wrap and store for 3-5 days!
